Tephrochronology (from tephra, Gk 'ashes') is a unique stratigraphic method for linking,
dating, and synchronizing geological, palaeoenvironmental, or archaeological sequences or …

The ability of crystalline zircon (ZrSiO4) to incorporate and retain trace element and isotopic
information, due to sluggish diffusion, makes it an indispensable tool for geochemists and …

Granitic—rhyolitic liquids were produced experimentally from moderately hydrous (1.7–2.3
wt% H 2 O) medium-to-high K basaltic compositions at 700 MPa and f O 2 controlled from Ni …

The Eocene epoch in the Great Basin of western North America was a period of profuse
magmatism and hydrothermal activity. During that period, the Carlin-type gold deposits in …

We present melt and mineral compositions from nominally anhydrous partial melting
experiments at 2–3 GPa on a quartz eclogite composition (G2) similar to average oceanic …

Experiments were conducted to study the temporal evolution of feldspar crystallization
kinetics during isothermal decompression. Pinatubo dacite was held at 780° C, 220 MPa …

Laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) mapping is a
rapidly expanding field in the geosciences because of the wealth of spatial information it …

Although many explanations have been proposed for the internal zonation of granitic
pegmatites, the most widely accepted model is attributed to RH Jahns. Jahns and Burnham …

Dacite tephras produced by the 1991 pre-climactic eruptive sequence at Mt. Pinatubo
display extreme heterogeneity in vesicularity, ranging in clast density from 700 to 2580 kg m …

This study focuses on the production of convergent margin calc-alkaline andesites by
crystallization–differentiation of basaltic magmas in the lower to middle crust. Previous …
